Question

A worker is paid Rs. 210 for 6 days work.
If his total income of the month is Rs. 875, for how many days did he work ?

Answer 1

Payment for 6 day's work n Rs. 210
Let payment for x day's work =Rs. 875
Therefore,:
$\begin{array}{ccc}\text{Payment (in Rs.)}& 210& 875\\ \text{Day's (work)}& 6\frac{6}{x}& \end{array}$
$\therefore \frac{210}{6}=\frac{875}{x}$ (constant)
$\Rightarrow 210\times x=875\times 6=\Rightarrow x=\frac{875\times 6}{210}=25$
$\therefore$ Number of days = 25
